Dear Gary, LF Group,

I suppose the more specific you are about your intentions, the more =
likely
Ofcom are to consider yours a well-planned application. So I intend to =
put
down specific modes. In my case I will put:

A1A - ordinary CW / QRSS
F1B - FSK modes like Jason and DFCW (maybe DFCW should really be F1A?)
G1B - PSK modes like PSK31 and Jason.

I will probably also specify that the maximum bandwidth of emission will =
be,
say, 200Hz, since this is compatible with the width of the band and =
other
signals in this frequency range.

As far as the ERP goes, I will go for the maximum -10dBW ERP. My
justification is that in order to do far-field field strength =
measurements,
one needs a reasonable field strength at a reasonable distance. -10dBW =
will
give you about 220uV/m at 10km, which is no more than adequate to do =
mobile
FS measurements reasonably easily.

By the way, is it possible to fill in and submit the form on line? As =
far as
I can tell, you can only download the pdf and send in a hard copy by =
post,
which will take a bit longer. Also, what about the tick-boxes where you
indicate "supported / not supported"? I suppose I should tick the one =
that
says "RSGB support"? I guess the "NoV issue" boxes are for Ofcom to
complete?

Hi Jim & LF,

There has been some discussion regarding emission codes relating I =
presume=20
to the section on the OFCOM SRP form requesting - BAND - MODE - POWER -, =

Surely it would be acceptable to answer in the box "All Permitted Modes" =
or=20
something similar.

What do you think guys ??

BTW - what are the correct emission codes for modes like PSK31 or Wolf, =
and
FSK / mFSK signals like DFCW and Jason?
